Title: XML parse error on subscription widget Last modified: August 30, 2016 --- # XML parse error on subscription widget * Resolved [Adrien L](https://wordpress.org/support/users/adrien-l/) * (@adrien-l) * [10 years, 9 months ago](https://wordpress.org/support/topic/xml-parse-error-on-subscription-widget/) * Hi guys, * First of all, thanks for this wonderful plugin. * Now, we are encountering a problem with the subscription form widget. On Firefox and IE (not exclusive, I just tested these guys), the landing page is complaining about a parsing problem with the form on newsletter/do/subscribe.php: * ``` Erreur d'analyse XML : balise ne correspondant pas. Attendu : . Emplacement : https://deontofi.com/wp-content/plugins/newsletter/do/subscribe.php Numéro de ligne 11, Colonne 51 : --------------------------------------------------^ ``` * So, Firefox doesn’t find the matching `` in do/subscribe.php, let’s add it! Here is what I get: * ``` ``` * That is what I _see_, meaning the html document is interpreted as a XML document, for some reason. * I am really lost, here. I guess it’s not your fault, as I don’t see anyone complaining for the same issue. We just fixed a similar problem on the RSS fedds that where not parsed correctly using the following plugin: [https://wordpress.org/plugins/fix-my-feed-rss-repair/](https://wordpress.org/plugins/fix-my-feed-rss-repair/) What it does is removing unexpected white spaces that corrupt the file, which may come from the theme. And we do have a shitty 2-3yo one (I’m working on the new one! Right when I’ll finish with this bug…). * So, config wise, we have w3 total cache (I tried to disable it, no change), newsletter, an outdated version of feed by mail (I’ll buy it for another year when I correct this bug), nginx, debian, full-SSL, and an outdated theme (required+ Foundation) that might be screwing around. * Please help us, nobody can subscribe. 🙁 Oh, here’s the URL : [https://deontofi.com](https://deontofi.com) * [https://wordpress.org/plugins/newsletter/](https://wordpress.org/plugins/newsletter/) Viewing 4 replies - 1 through 4 (of 4 total) * Thread Starter [Adrien L](https://wordpress.org/support/users/adrien-l/) * (@adrien-l) * [10 years, 9 months ago](https://wordpress.org/support/topic/xml-parse-error-on-subscription-widget/#post-6467455) * No input on the topic? Seeing that I’m the only one with this bug, I guess it must come from another plugin or theme, but I’d really appreciate your advice on its resolution. * Thanks, Adrien * Plugin Author [Stefano Lissa](https://wordpress.org/support/users/satollo/) * (@satollo) * [10 years, 9 months ago](https://wordpress.org/support/topic/xml-parse-error-on-subscription-widget/#post-6467456) * Try to deactivate other plugin to see if the problem solves. Have you a caching or rss related plugins? Start from them. * Stefano. * Thread Starter [Adrien L](https://wordpress.org/support/users/adrien-l/) * (@adrien-l) * [10 years, 8 months ago](https://wordpress.org/support/topic/xml-parse-error-on-subscription-widget/#post-6467479) * Hello, * So, the bug was caused by Piwik. In the plugin WP-Piwik, we can choose various ways to link WordPress to Piwik, including PHP or by URL. I chose PHP, first, which caused the bug. By URL, it works fine. * I spent days on this issue. Plugins compatibility is a pain in the ass. I’ll do a better investigation to check which exact WP-Piwik parameter makes your plugin break when I set up the new version of the website I’m working on. For now, philosophy “it works, don’t touch anything”! * I suggest you put a line about this issue somewhere, that kind of php being sent as xml bug is just impossible to track down… * Thanks anyway for your plugin, which brings us hundreds of views everyday! 🙂 Adrien * Plugin Author [Stefano Lissa](https://wordpress.org/support/users/satollo/) * (@satollo) * [10 years, 8 months ago](https://wordpress.org/support/topic/xml-parse-error-on-subscription-widget/#post-6467485) * Thank you!
